Abstract

In methods of making disposable, flexible containers for fluent products, methods of sealing the flexible containers when such containers include expansion materials, are disclosed. The methods include forming a partially completed container blank that has layers of flexible materials. The layered structure includes a first space for a fluent product, and a second space for an expansion material. The methods of sealing the flexible containers include adding an expansion material into the second space and pressing parts of at least some of the layers together to close off the second space.
